Phase Demodulation Simulation

Instructions for Phase Modulation (PM)

• Step 1: Click on 'Generate Message' button to generate input message signal
• Step 2: Then click on 'Generate Carrier' button to generate carrier signal. The carrier frequency has to be more than the message frequency and You can change frequencies using sliders
• Step 3: Click on 'Generate Phase Modulated Signal' button to generate Phase Modulated Signal
• Step 4: Click on the 'Show Frequency Spectrums of PM' button to see spectrums of the PM signal
• Here, β represents the phase modulation index, given by β=kp*Am​, where Am​ is the amplitude of the message signal (assumed to be fixed), and kp​ is the phase sensitivity of the modulator
